Advice needed - looking to earn CS credits

[jonsnow]

Hello,

I am a prospective international applicant living outside the US with a background in economics. I have both BSc and MSc along with a few years of professional experience and I do not have a single college credit in Computer Science (CS).

I am looking to pivot into CS and Georgia Tech's OMSCS is my top choice currently for which I've already applied but my application will most likely be deferred to Spring 2021.
I need to take a handful of accredited core CS courses online to demonstrate objectively documented basic capability and knowledge in CS.

Below are the courses that I am looking to take:

C++ Programming (or Intro to CS in C++)
Java Programming
Data Structures & Algorithms
Design and Analysis of Algorithms
Databases

The list can be slightly different but I believe these are the most important courses.

What option is most suitable for me? I'd really appreciate your expertise and advice on how I can take these courses and earn CS credits quickly and affordably.

Thank you.
